What Size Is My Water Heater?

The size of your water heater can typically be found on a white sticker with the manufacturer’s information OR on the yellow energy star label. If you cannot locate the size of water heater you can always send the serial number to a licensed plumber to look up the exact water heater you have. If you have a gas water heater the type of flue – metal or PVC – is also valuable information to provide a licensed plumber when pricing a water heater replacement.
